Abstract: 275,579. Titan Co. Aktieselskabet. Aug. 3, 1926, [Convention date]. Titanium sulphates and salts in general.-In the treatment of titaniferous materials, such as ilmenite, rutile, or titanite, with an acid, such as sulphuric acid, to effect solution, a reducing agent is added to the material to be treated or to the acid before or during the treatment, to expedite the reactions which take place. As reducing agents may be used magnetic or common pyrites, the products obtained by heating pyrites to ignition with ilmenite, iron, or iron oxide, or by heating together two or more of pyrites, magnetic pyrites, sulphur, titanium compounds, iron, or iron compounds such as iron sulphate, at temperatures between 400 and 1000‹ C. and generally at 700-800‹ C., with or without rapid cooling, as 'by immersion in water, of the products. Ilmenite subjected to a reducing process may also be used alone. Iron used may be wholly or partly replaced by zinc, aluminium, antimony, silicon, titanium, magnesium, or alkali or alkaline earth metals. Alternatively, sulphur may be admixed with the titaniferous material to be treated, or the latter may be pretreated at 700-800‹ C. with sulphur vapour or a gas mixture containing sulphur to introduce sulphur thereinto. Additionally sulphuretted hydrogen may be added during the process of solution.

IPC: B08B9/08
Filed: 1943-10-28
Abstract: 573,072. Washing casks &c. ROBERTSON, D. C. Oct. 28, 1943, No. 17831. [Class 21] In a washing- machine, e.g., foi casks and barrels, a low - pressure steam valve B, a valve D admitting water at high pressure from a pump and a valve C connected to the suction side of the pump are operated in timed relation by the up- and-down movement of a lever E connected to the valves. In the rest position lever E engages by a roller N in a notch in a cam F. When this cam is rotated at a predetermined velocity lever E is rocked about its pivot A<1> by engagement of its roller N with the periphery of the cam until one complete revolution of the cam has taken place when the movement stops. Movement of the cam is initiated by raising a hand lever G which rocks lever E downwards tbereby rotating a pawl Y which disengages from a projection X on a rod R which is then vertically reciprocated by a continuously running cam M so that a lever K is rocked, and by means of a chain drive rotates cam F step by step in counter-clockwise direction until roller N again engages the notch in cam F and the rotation ceases. The stroke of rod R and therefore the rate of rotation of cam F is adjusted by a nut r<5>. A casing Z is provided to prevent unauthorised acceleration of disk F.

Sewing-machines: cords. braids, and the like. attaching; folding-devices.-A sewing-machine is provided with means for inserting a tape or strip into a pocket formed by the folded parts of a fabric so that parts of the tape are in tension and other parts are untensiosed during sewing and is described in connexion with the insertion of an elastic strip in the waist-band of a skirt or like garment. The strip T, Fig. 3, is led to the needles 4, 5 along a guide 30 which is inclined to the line of stitching and is of channel shape, and under a block 35 carried by a spring-steel arm 38 which presses down on the strip with adjustable pressure and is pushed upwards by a rod 48 under control of the operator. The guide 80 is carried on a folder 21 for folding the edges of a waist-band B, and a folder is provided for folding the edge of the main fabric F. In this arrangement, two needles 4, 5, are used, making rows of stitches s, s<1>. When sewing those parts of the band that are intended to be flat, such as at the front of a skirt, the strip is fed along with the band and main fabric without tersion so that one edge is caught by the stitching s, and in sewing those parts of the band which are drawn or fulled, the block 35 is allowed to press on the strip thus causing it to stretch and become narrower in width and also to change slightly its direction of feed owing to the inclination of the guide, and so miss the stitching s. The machine may also be used for securing the strip in the 'pocket formed by folding over the edge of the main fabric F, as shown in Fig. 12, where 'one needle only may be used to stitch the turned edge f<3>. In further modifications, the guides and folders are arranged parallel to the line of stitching and the needle avoiding movements of the tape caused by narrowing it by tension, or they may be arranged to produce the article shown in Figs. 18 and 19 in which the elastic strip is enclosed in the band B and both are stitched to the folded edge of the fabric F. In this construction, the needles at all times penetrate the elastic strip which is fed with. out tension over the part from b to b' and with tension at the puckered parts. Reference has been directed by the Comptroller to Specification 112,638.

Filed: 1942-12-23
Abstract: 561,957. Welding air - screw hubs. ROSE STREET FOUNDRY & ENGINEERING CO., Ltd., and GORDON, S. H. Dec. 23,1942, Nos. 18279/42 and 14667/43. [Classes 83 (ii) and 83 (iv)] A resistance welding machine for welding together the halves of a metal shell provided with a number of blade holding arms spaced around its periphery to form a hub for an airscrew is provided with work-holding clamps, each of which comprises an electrode block or blocks shaped to fit the external surface of the half blank and a number of clamping blocks, one for each arm which are provided with power-operated means for pressing them against the inner surfaces of the arms to clamp them against the electrode blocks and are movable into and out of the arms independently of the power-operated means. The halves of a hub each provided with four relatively long cylindrical arms 10 are secured respectively to the movable platen 22 and to an adjustable fixed platen 20 through castings 18 each provided with a copper or like electrode block 14 for each arm in which the halves, after machining, are secured by a clamping block 38 for each arm which engages the inner surface of the arm and is mounted on a bar 36 pivoted at 34 to a lever 30 pivoted in the part 18 at 32. The lever 30 is pressed down against the action of a spring 40 so as to bring the block 38 against the inner surface of the arm by an hydraulic ram 28; the bars 36 may be biassed outwardly by springs 42 to facilitate insertion and removal of the work and may be forced inwardly by plungers 44 pushed in by a hand-operated cam ring. The clamping blocks are provided with two cylindrical convex portions 39 to exert a wedging action to ensure intimate contact between the blocks and the blanks.

Patent GB-638201-A (GB)
Title: Automatic bread toaster
IPC: A47J37/08
Filed: 1947-07-10
Abstract: 638,201. Electric toasters. SUNBEAM CORPORATION. July 10, 1947, No. 18282. Convention date, Oct. 9, 1941. [Class 28(i)] [Also in Group XXXVII] An electric toaster in which a bread slice dropped into a bread receiving position initiates a timed toasting period after which the slice is returned to the original position, has an arm 56, 56 triggered by the bread slice closing the circuit to electromagnet 95 through contacts 50, 50. Arms 65, 66 joined to shaft 64 move down from the bread receiving position to the toasting position by action of tensioned spring 67, and cause in turn main contacts 45, 45 to close and contacts 50, 50 to open. Heating elements 32, 32 and motor 80 are thus switched on and electromagnet 95 is de-energized. The motor 80 driving ratchet wheel 74 in a counter-clockwise direction causes cam 70 to engage and depress arm 93 against compression spring 97 and allows contacts 100, 101 to close. In addition, movement of arm 69 upwards twists spring 68 on shaft 64. As the pin 74a, not shown, approaches the top of its travel, lug 71 is released, allowing arms 65, 66 to swing back to the bread receiving position due to the stronger spring 68. The spring 67 also becomes twisted for the next operation and main contacts 45, 45 are separated. The motor 80 continues to drive wheel and pin 74, 74a due to contacts 100, 101 still being made. Pin 74a, having passed over top centre, causes arm 69 through link 77 to draw ratchet wheel round until pin 74a is at the bottom of its throw and contacts 100, 101 are opened, thus breaking supply current to the motor. Removal of the toasted bread releases insulating members 53a, 53a, which drop to their normal position, resting on tubular member 52, 52. Shortening of toasting time by speeding up of the motor is effected by control of rheostat 81 through heat sensitive bi-metal bar. The normal toasting period and sequence may be interrupted manually by handle 107.

Title: Improved process for the manufacture of sheet glass
IPC: C03B15/08
Filed: 1922-07-05
Abstract: 182,805. Rowart, E. July 11, 1921, [Convention date]. Drawing.-In a process of drawing glass in continuous sheets, the width of the sheet, is preserved by drawing the edges from metal which issues from channels in refractory blocks, and means are provided for regulating the temperature and consistency of the body of the metal and the temperature of the sheet as it is drawn upwards. The metal flows from a tank 1, Fig. 1, under a floating bridge 4 into a forehearth 2 where the depth of metal is small compared with that in the tank. The position of the bridge 4 can be adjusted in order to regulate the condition of the metal in the forehearth. The drawing chamber is formed by an open-ended box or casing 12 of refractory material which is adjustably supported on walls 8 extending downwards from the crown of the forehearth, a second chamber 16, which contains the drawing-apparatus, resting on the casing 12. The drawing- chamber proper 14, is formed by walls 13 in the interior of the chamber 12 which are separated at the top and extend downwards to the surface of the metal, thus delimiting an area of metal from which the sheet is drawn. At the sides of the chamber 14 are adjustable shields 18, Fig. 7, which control the extent to which the hot gases circulate over the side portions of the metal and thus assist in regulating the temperature of the metal in the drawing-area. In front of the shields are " plungers " 24 consisting of blocks of refractory material which dip to an adjustable extent in the metal. A " plunger " has a recess 27 the lower wall of which is wedge-shaped, and is perforated with a passage 25 through which passes the metal from which the edges of the sheet are formed. In operation, a bait is lowered through the space 35 at the top of the drawing-chamber and after the metal has adhered, is drawn upwards into the chamber 16 in the usual manner. The bait has depending portions at its ends which enter the recesses in the " plungers " 24 and draw the metal from the passages 25. The edges of the sheet are thus drawn from separate portions of metal which unite with the body of the sheet as they leave the passages 25. The temperature of the sheet is regulated as it is drawn upwards by means of metal coolers 21<1>, contained in the drawing-chamber 14, through which water is circulated. Curtains or shields of refractory material may also be used to control the radiation from the surface of the sheet. In a modification, shown in Fig. 2, the metal from which the sheet is drawn is contained in a box-like structure 37 of refractory material which dips into the metal and communicates with the body of the tank through grooves and passages 39, 40. Metal passes through these grooves into the interior of the structure, thus obtaining a comparatively small volume of metal at the temperature necessary for drawing.
